The site is located <br />south of State <br />Highway 205 <br />and west of Hansen Road in Tracy, <br />California. A <br />plot plan and <br />vicinity map <br />showing the approximate location of <br />the proposed <br />subdivision and <br />test sites are <br />presented on Plate I of this report. <br />10 <br />39 <br />- P-7 <br />An original set of percolation tests for this site was performed in November <br />1983. The three tests submitted in this report are in addition to the original <br />tests. They were requested by San Joaquin County Health Department. They are <br />requiring a total of one test per three lots. The scope of our services was <br />outlined in our phone conversation of March 26, 1984. <br />The three percolation tests were each approximately 3 feet deep, 6 inches in <br />diameter, and lined with perforated Orangeburg pipe. The percolation holes were <br />initially filled with water and allowed to soak for a period of 24 hours. The <br />tests were performed by filling the hole with water to a fixed referenced point <br />and gllowing the water to percolate for a period of 1/2 -hour intervals. A final <br />reading was taken at the end of the 4 -hour period. The percolation test results <br />are presented on the following Table: <br />Percolation Test Results <br />Percolation <br />Depth of Hole <br />Rate <br />Test No. <br />(inches) <br />(min/in) <br />Lot No. <br />P-6 <br />36" <br />10 <br />39 <br />- P-7 <br />36" <br />I 125;V <br />35 <br />P-8 <br />36" <br />42 <br />33 <br />
